T (LU whom t may concern.-

Beit known that l, ISAAC ANDERSON, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented a new and useful Lock, of which the following is aspecification.

This invention relates to locks; and the principal aim of the inventionis to provide a lock which is reversible, so that it may be applied toeither edge of any door, the said lock having a movable key-socket whichis capable of being reversed wit-hout detaching the lock-case from thedoor.

A further object of the invention is to provide a lock-case with arotatable portion having a keyhole at one side only, the' said rotatableportion being capable of being reversed for bringing the keyhole eitherto the outside or inside of the door, thus adapting the lock to beworked from either side of the door, the arrangement being such thatwhen the keyhole is brought to one side of the door the lock may not beworked from the opposite side of the door.

A further object of the invention is to provide means for locking therotatable portion of the case and other means for closing and concealingthe keyhole.

TiVith these and other objects in view the invention consists in animproved lock enibodying certain novel features and details ofconstruction and arrangement of parts, as hereinafter fully described,illustrated in the drawings, and finally pointed out in the claimshereto appended.

In the accompanying drawings, Figure lis a perspective view of theimproved lock, showing also a portion of a door to which the lock isapplied. Fig. 2 is a horizontal section through the same, taken in linewith the sliding clutch. Fig. 3 is a vertical longitudinal sectionthrough the same, showing the two positions of the bolt in full anddotted lines. Fig. at is a detail perspective view of the rotatablekey-socket. Fig. `5 is a similar view of the sleeve surrounding saidsocket. Fig. G is a detail perspective view of the lock-bolt. Fig. '.7is a similar view of the tumblen Fig. 8 is a detail perspective view ofthe removable bracket in which the bolt and tumbler are mounted. to beused in connection with the lock. lO is a plan view of the lockdetached.

Similar numerals of reference designate corresponding parts in theseveral figures of the drawings.

Referring to the accompanying drawings, l designates the lock-case,which may be formed in one or more pieces and which coniprises thespaced parallel side'plates 2, for einbracing the edge of the door uponopposite sides, and the face-plate portion 3, which is let into theswinging edge of the door so as to lie flush therewith, the saidface-plate 3 being formed with the openin g 4, through which thelock-bolt reciprocates.

In order to' carry out the present invention, the lock-case is providedwith a substantially rectangular recess 5, extending back from theface-plate 3. The base of this recess 5 is provided with a iiooring 6,formed by extending a web transversely across between the side plates 2,said web connecting the plates rigidly and serving to strengthen thelock-case. rlhe upper portion of the recessl 5 is partially covered by asegmental web 7. The web or flooring 6 is provided with a circularopening S near its center, which forms a bearing for a dependingtrunnion or short spindle 9 on the bottom of a rotatable key-socket l0.This key-socket is preferably of cylindrical form and its upper edge orend is rabbeted, as shown at ll, to engage, the segmentel web 7, abovereferred to. The cylindrical key- Fig. 9 isa similar view of a keeperFig.

- socket is thus mounted within the lock-case so as to turn upon avertical axis, and it is provided with a central cavity l2, in which thebit of the key may work, and also with a keyhole 13, leading outwardfrom said cavity to the periphery of the socket. By means of thisconstruction the cylindrical key-socket may be rotated so as to bringthe keyhole to either side of the door, and this may be done while thekey is in the socketA and without removing the key, the key beingemployed to turn the socket, although the socket may be turned withoutthe aid of the key.

A sleeve 14 surrounds the cylindrical keysocket and is provided with akeyhole l5, which may be brought into alinement with ICO the keyhole inthe socket-piece. The sleeve 14 is mounted loosely on the key-socket 10,so that it may be turned around the same, thus enabling the keyhole 13to be covered and concealed. Vhen the sleeve is turned to the desiredposition, it may be held locked by means of a sliding clutch 16 in theform of a metal strip sliding behind one of the plates 2 of the case andhaving a wedge-shaped end 17 for engaging between the sleeve 14 and thelock-case and provided at its opposite end with a lip 1S, by means ofwhich it may be slid into and out of engagement with the sleeve 14:.This sliding clutch is preferably arranged upon the inside of the door,and by jamming in between the sleeve 14 and the lock-case the sleeve isheld against rotation.

19 designates the lock-bolt, which slides at its front end through theopening 14 in the lock-case and at its opposite end is slidinglysupported in a bracket 20, removably tted within the lock-case and heldtherein by suitable fastenings. This bracket 2O is provided with asegmental base portion 21, which embraces the upper end of thekey-socket 10 within the rabbet 11 and serves, in connection with theweb 7, to hold the key-socket in place.

22 designates the lock-tumbler, lwhich is fulcrumed at one end uponatransverse horizontal pin 23 on the bracket 20. This tumbler comprisesspaced cheek portions or plates 2l, which straddle the bolt 19, andthese plates are connected by means of a cross-piece 25 at their freeswinging ends, the said crosspiecebeing adapted to engage with one ormore notches 26 in the upper edge of the bolt 19 for holding thelatterin or out. The bolt is also provided in its upper edge with anotch or recess 27, in which the transverse pin 23 is received and whichpermits the lock to reciprocate without being interfered with by saidpin. The side plates or cheek portions of the tumbler extend below theplane of the key-notch 28 in the bottom edge of the bolt, in which thebit of the keyis received for reciprocating the bolt, and thecylindrical keysocket 10 is formed in its upper end with notches 29,arranged at opposite ends of the cavity in which the bit of the keyworks, the said notches 29 being adapted to receive the bottom edges ofthe side plates or portions of the tumbler when the latter is depressed,the tumbler thus simultaneously locking the bolt and the key-socket andpreventing the latter from being turned. y

30 indicates a serpentine spring interposed between the top of thetumbler and the lockcase for pressing the tumblerinto engagement withthe bolt and key-socket. Any forni of keeper 31 maybe used in connectionwith the lock above described.

From the foregoing description it will be seen that the lock-case isprovided with what may be termed a rotatable portion, said portionhaving been also heretofore designated as the key-socket.7 It will beseen that this rotatable portion or key-socket may be instantly reversedfor bringing the keyhole of the lock either upon the inside or theoutside of the door, and that when said keyhole is turned to one side ofthe door it will be impossible to unlock the door from the oppositeside, as there is no place to insert the key. It will be apparent alsothat by means of the sleeve which surrounds the rotatable portion of thecase or the key-socket the keyhole may be covered and entirely concealedand the sleeve itself may be locked against fraudulent manipulation bymeans of the sliding clutch described. To facilitate the turning of thesleeve 14, the latter is provided with a socket or opening 32, adaptedto be engaged by a pin, stud, or other projectio 33 on the key, as shownin Figs. 1 and 10. In addition to these advantages the lock isapplicable to either edge of a door, not requiring to be made in rightsand lefts.

Any desired ornamental finish may be i1nparted to the lock-case, and itwill be understood that the lock is susceptible of changes in the form,proportion, and minor details of construction, which may accordingly beresorted to without departing from the spirit or sacrificing any of theadvantages of this invention.
